COIN-CONTROLLED LOCK.

Applicationfiled January 14, 1922. Serial No. 529,223.

This invention relates to locks and, more particularly, to coin controlled locks such as are adapted to be used upon the doors of pay toilets, or the like, so that the collection of the coin is automatically accomplished latches which do not include the coin operable mechanism.

One object of my invention is to simplify a device of this character while securing advantages of operation not found in the present structures. m

Another "object of my invention is to provideimproved means for closing the coin slot when the door is open and keeping it closed after'the door has-been again closed and until it is opened from the inside by the occupant of the room. I contemplate the provision of means for accomplishing this function which shall be, to some degree,

. independent of the latch or lock bolt, so that once this mechanism has been set to close the slot, the bolt may still be operated from the outside of the door independently thereof and without releasing it so that the slot closing mechanism will not, thereby, be restored to its normal position.

"Further objects of my invention are the provision of improved means for holding the coininoperative position to withdraw the latch bolt from the outside of the door until such time as the occupant enters the roomand the latch bolt is retracted by contact with the strike plate; the provision of 1 a meter or counter to register the number of times the room is used, which register will preferably be operated by part of the slot closing mechanism rather than by the operation of the bolt; and improved, means for securing the operating parts of the structure within the 'case, securing the case itself upon the door, providing for the withdrawal of the coin therefrom and the provision of a door knob of improved construction.

To these and other, ends, the invention consists of the novel features and combinations of parts to be hereinafter described and claimed. In the accompanying drawings:

In the preferred embodiment of my in vention illustrated in the drawings, I'have shown a door 1O having a lock case 11 mounted thereon. Protruding from the lock case is the head 12 of a lock or latch bolt which cooperates'with a-strike plate 13 -of approved form mounted upon the door the greater part ofthe operating mechanism is mounted and a cover 16 adapted to be applied to the base plate after the latter is mounted in its proper position. This cover plate is provided with a strap .17 secured to the interior thereof which, in turn, may be secured to the base plate to hold the cover in position, and with two recesses 16 to receiie the pins 15 on the upper edge of the base plate. At the upper part of the cover, is provided a coin slot Y18 and rotatably mounted upon the front face of the cover is the outside door knob 19. Se'curedto the stem 20 of the knob is a rollback 21 which, as will be more fully described hereinafter, operates to retract. the bolt. Below the knob the cover plate is promechanism.

secured connected by a front late or Web 31 and the vided with anopening 22 within-whichis fitted-a square plate 23 havin a pair of lugs 24 at-the' upper side thereo adapted to overlap one marginvof the opening and provided "adjacent its lower edge with a key operated lock 25 which operates a locking member'26 adapted to engage a lug 27 adjacent the lower side of the opening 22 to l'ockthe plate in position. Through this opening, when the plate 23 is removed by an authorized person having the proper key to fit the lock 25, the coins may be removed which .have been collected by the lock The main part of the operating mechanism of the lock is, as has been statedrheretofore, mounted upon the base late secured upon the outer surfaceof the cor. 'A'bolt guide consisting of a pair of straps 29 and 30 is to the plate 15. ,These straps are strap 29 is closed at t e rear side thereof by the end piece 32. -Withi-n the guideway thus formed is slidably mounted the bolt 33,hav-

ing the beveled head 12heret0f0re'referred the plate 31, as best shown in Figs. 4 and 7.

In order that this member may be properly guided in its movement, a strap 40 is'mounted upon the member36 and offset to extend upon the opposite side of the plate member 31 so that the operating slide will have an even sliding movement upon this plate. Upon the ends of thisstrap 40 are formed two talons 41 and 42 adapted to 'be engaged by the arms 43 and 44 of the ollback 21. The strap 49 is provided upon 1 rear edge with an arc'uate recess 45 adapted to engage the edge of the coin as shown in Fig. 5. The front face of-the bolt is adapted to bear against the guides 29 and 30 at the portions thereof adjacent these two members, but between them the bolt is sli htly recessed or cut away from its front ace to provide a pair of shoulders, one of which is shown at 46 In Fig. 5. This shoulder is provided with a recesed portion 47 adapted to eflfect a posi- .tive release, at the proper time, of a coin delivered by the chute 38. It will be obvious that when a coin is deposited in the opening 18, passes down through the chute38 and lod es between the shoulder 46 and recess 45, 1f the outside knob is turned to move the slide from the dotted line position shown iu'Fig. 5 to the full line position shown in that figure, this slide will act through i the agency of the intervening coin to retract the bolt by means of the engagement of the coin with the member 40 attached'to the slide and-the shoulder 46 formed upon the. bolt. 1 Upon the upper surface of the bolt is slidably mounted an operating slide 50. This slide is also received and guided within the strap members 29 and 30 while it is supported upon the upper edge of the bolt as shown in Fig. 7. The slide is provided with a slot or cutout portion 51, thus providing an opening through which thecoin is adapted to pass as it leaves the chute 38. This opening terminates in the shoulders 52 and 53% shown more especially in Figs. 8 and 9, and it will be apparent that when the arts are moved from the position shown in ig. 4 to that shown in Fig. 5, the edge of the coin 55 I will engage the shoulder 52 and will also move the slide rearwardly at the same time that the bolt is retracted. Adjacent the forward portion of the slide at the rear edge thereof is provided a recem or cutout 54 adapted to receive one end of a lever 55- pivoted at 56 upon the plate 15. The upper end of this lever passes between a pair of laterally extending ears 57 and 58 formed.

upon a slot controlling slide 59, having at its upper edge a laterally extending lip 60 which is adapted in the position shown in Fig. 5 to lie just belowthe coin slot 18 and above the mouth of the chute 38 to prevent, when in this position, the insertion of a coin therein. The slide 59 may be operatively mounted upon the plate 15 in any approved way. In the form shown the slide is provided with a slot 61 which receives the shanks of a air of screws 62 and 63, which as will be obvious will permit the member 59 to enjoy a free sliding movement.

Pivotally mounted at 64 upon the supporting plate 15 is a second lever'65, one end of which is connected by a spring 66 to the upper arm of the lever 55. The lower end of this lever 65 is provided with a hook 67, the end of which is adapted to rest upon the upper surface of the operating slide 50 as this slide is being moved from the position shown in Fig. 4 to that shown in Fig. 5. The slide is also provided'at its rear edge with an elongated recess orfslot 68 which terminates at its rear= end in the shoulder 69. lVhen thisslide is drawn rearwardlyby gagement of the lower.,end':of this-lever in I I the slot 54 in the operating slide: As shown inlFigs; 4 and '6, spring is relievedby contactfof the hook 67 with the upper surface of the slide 50. The spring '66 1s therefore brought under tension and when the edge of the hook 67 lies opposite -the opening 68, the hook will drop downwardly into engagement with the shoulder 69 to retain the .slide in this retracted position.

A register or counter70 is shown secured to the supportingplate 1 5 and is'prov'idedwith an operating arm or crank 7 1. A link 72 connects this crank to an arm 73 upon the lever 55 so that when this lever is moved from the position shown in Fig. 4 to the position shownin Fig. 5, asit will be, by the action of the outside knoband the operating slide 50, the counter will be operated through the link 72' to register the number means of the coin.

ofi times that the slide 50 is drawn back by If when the parts are m the Position ih the supporting plate 15'and provided with shown in Fig. 5, the outside knob is released, as it-will be in the ordinary use of the omechanism, the operating slide 50 will be retained in its rearward or retracted position while the spring 34 will again carry the latchbolt. to its protracted position.

The member 36 and the outside knob 19 will 35 also be returned to their original positions by means of the spring 74 which is attached to the guide I strap 30 at one end and to the member '36 atthe other. When this occuts, the coin will drop down to a lower po- 40 sition so that it will. no longer be engageable with the plate 50, butwill still be retained between the. edge of the. member 40 and the shoulder 46. To force the cein to this lower position so that itwill *no longereng'age the slide,', a. strap 75 is mounted upon this slide and is'prOVidedwith a slightly oflset shoulder 7 6 which projects overthe slot 51 and, engaging the edge of the coin in 'the position shown in Fig.

0 5, forces the coin downwardly as the latter is moved tothe right by the shoulder 46.

It will be'obvious that with-the coin still I held in position between the operating'memif by anychance a.

ber and the shoulder, person after turning the knob releases it before opening the door, he will not be locked out as the latch boltcan again be, retracted time after time by the coin to open the door, without, however, having any efl'ect upon the slide or the-mechanism controlled thereby, including the counter or register 70. When, however, the personenters the room and closes the door, the latch bolt will be. retracted by the engagement of thebevelled head thereof'with-the len h the bolt strike plate and as at this time the operating member 36 remains stationary, the coin will be'allowed to drop into a proper receptacle or the lower part of the case 11 for collection.

The door-is now in closed position with the slot closed against the insertion of a coin and in ordinary use it will best be desired to open the door from. the inside. For this purpose an inside knob 77 ismounted upon the door by means of the plate 78 secured to the door. by screws 79- assin therethrough from the outside '-t ereo which screws are ut into position beforethe a plication 0% the supporting plate 15. T1e

plate 78 is provide with a centraliopening 80, into which fits a reduced portion 81 of x the shank of the door knob, and to the face of this shankis' secured a plate 82, thereby clamping the edge of the opening in the-- plate 7 8 between a shoulder .83 on the knob shank and the plate 82 upon .theface of the shank. The plate 82 is provided with a square 0 ening into which is fitted a square shaft or olt 85, one end of which passes into the hollow shank of the knob, the other end. assing into a sleeve 84 rotatably mounted ,best shown in Fig. 6, the rear face of the bolt closely abuts the mounting plate 15 adjacent the bolt end, but intermediate itssli ing portion 91 providing the shpulders 92 and 93. Within this slottedportion between the rear'faceof the bolt and the front face of the supporting the lower. end of-the lever. I through-a slot 54 in the operating plate 50. Also mounted within this space is a lever. 94

.pivoted to'the supporting plate at 95 and J1 lyprojectingfinger 96in aving an upwar pOSltIQII to engage the lower arm'of the lever 65. An edge face'97 of the other end of this jisprovided with a cutoutor plate 15 lie the plate '90 and the rollback 86 ju t d be and 55 which" passes lac lever lies against a" straight portion 98 of the rollback 86 so that thisjlever .will he door to emerge from theroom, so that the parts are thereby set for a subsequent operation when a proper coin is dropped in the slot. At this time the slide 59moves tothe position shown in Fig. '4 to. uncover the mouth of the coin chute 38and the counterarm 7 1 is dropped from the position shown and the shoulder 46 will be separated too the parts in the position shown in Fig. 4,- it will be apparent that it is im ossible to far to retain this coin in position to operate thebolt. In some cases, however, the bolt might be 0 erated by turning the outside knob slight y so that the recess would be moved closer to the shoulder 46 prior. to the insertion of the. coin in the slot. The ofiice of the laterally extending lip 37 is to prevent any fraud, 1n this res ect as, when theknob is turned to o erate t e member 36, the lip 37 will becarried over the mouth of the coin chute 38 so that any' coin which will be permitted to pass into the chute will fall idly through. the lock mechanism and will not be retained between the shoulders 45 and46 in position to operate the bolt.

The operation ofm'y improved mechanism is -as followsi The door being closed and retract the latch by rotation of t e outside knob 19, as the operating member 36 has no connection with the latch bolt except through the intervention of theproper coin,

When, however, the proper coin is inserted into the slot 17 and drops through the chute 38 to the positionshown in Fig. 4, it establishes a connection between the edge of the recess 45 in theoperating member 36 and r the shoulder 46055 the bolt. The bolt may now be retracted by the rotation of the knob.

The coin also at'this time, by contact with, the shoulder 52 ofth'e slide 50, drayvsv this slide rearwardly, together withthe lower end of 'the lever 55 until the lower hooked .end'67 of'the lever engages the.shoulder 69 in this" slide. The parts are now in the position shown in Fig. 5,, the up er end. of

the lever 55having moved thes ot closing slide 59a the right into operative posi-.

tion to close the slot and having drawn the counter arm upwardly to actuate the counter mechanism and indicate the reception of the coin. 'The door may now'be opened and the 'knobfreleased, the spring 74 draw- 'ing the knob and operating member 36 to 'thezright to their normal positions and the bolt .bein'g again protractedby the spring 34: Should, however, the operator release the knob before the door was opened so that right, as shown in Fig. 5, by the ressure of the edge of the shoulder 46. e right hand edge of the coin contacts'with thepart 76 of the plate 75, and while the coin is forced down to a position below this plate,

it is still retained between the shoulder 46 and the member 40 upon the operating mem-. ber- 36, as shown at 103 in Fig. '4. The

part 76 at this time closes the lower end of the coin chutef. The slide 50 is, of course, held in the position shown" in Fig. 5 by means of the engagement of the hook '67 therewith, as are also the slide 59, the lever 55 andthe counteriarm 71, all of which are controlled by the slide. When a person passes into the room and closes the door,

the latch bolt is retracted by operation of the strike and'the shouldr 46 moves away lowing the coin to dropout of operative position into a proper receptacle, the remaining parts, however, still being retained in the position shown in Fig. 5. In this position, the lower arm of the lever 55 con-' tacts with the up er end 96 of the leverv 00 from the edge of the member 40, thus .al-

94 so that when t e occupant of the room 77 to withdraw the latch bolt, the rollback wishes to emerge and rotates the inner knob 86 rotates the-lever 94 and thus moves the hooked end of the lever 65 out of en age. ment with -the.shoulder 69 on the sli e50,

the s ring 66 restoring the slide. and associate mechanism to their normalwpositions.

The lock is now set for a succeeding operation.

j. -It will also be obvious that I, have pro-' yided both inside and outside-knobs with operating mechanism which enables them to be rotated in either direction tofretract the latch trolled lock r I It is necessaryat' times for an. attendant tobe able to open the door from the out sidev without the necessity of inserting the coin. into the slot. This may be done by bolt, which is not usual in a coin -con-' meansof a proper key inserted through the keyhole 100 in the cover plate 11, the key bit '101 engaging a {depending pin, 102 upon the lower edge of the It 33.
